Securing the wifi router is the first step homeowners need to take to protect their smart home. During use, it is recommended to update the router’s firmware and always use a complex password for the wifi router. If the router manufacturer does not provide new firmware, users should consider replacing it. Just like not checking your bank account from public wifi, homeowners should avoid accessing smarthome from an open wifi network, but if you need to remotely access your home, use a private network. Using a separate wifi for smart home systems is necessary because sharing a wifi system has many potential safety risks. Smarthome prioritizes the system to be able to self-alert to abnormal intrusion to ensure safety, so users should use devices with automatic alarm setting feature. When there is an unusual intrusion, a notification will be sent to the homeowner’s phone immediately. In smarthome, not only home lock, smart home control applications need abnormal login warning feature, this helps homeowners recognize the risk of network attack to implement instant protection options. then. In a smart home, if there is a smart speaker with a screen or camera, users should consider turning off or covering the camera when there is no need to use it. This is similar to the fact that many people have a habit of covering the webcam on their laptop to avoid unfortunate images being recorded. Smart devices of unknown origin are at risk of being installed with spyware, which is easy to lose control and have data stolen. To be safe, it is recommended to use equipment from reputable companies, need to check the company history, product support period. From this information, a decision can be made whether to buy the product or not. And more specifically, it is very important to check the owner of the servers that will contain his home’s information because most smarthome devices used in the home communicate with servers in the cloud. In the process of studying the operation of the smart home control system, security experts have discovered serious security holes. Security flaws in the cloud infrastructure and remote code execution, causing a third party to acquire the “super user” right to access and control the smart home system. Immediately, the above findings were shared with smart home providers to immediately address these dangerous security holes. With a smart home, each device inserted into the smarthome can also be a point for network attackers to take advantage of, intrude on the home system …, so smart home security is very necessary for those who want Design your own smart home.

Break boundaries in Internet access Elon Musk’s project of covering the Internet around the Earth has begun for users to sign up for testing. You can be one of the first to use this service even while living in Vietnam. Starlink’s ambition is to use 12,000 low-end satellites to cover the Internet to every corner of the globe. So far, this project has been successful in covering all over the Americas with a total of 1,261 satellites in orbit. The billionaire Elon Musk’s satellite Internet project also targets Vietnamese users. Currently, Starlink started allowing users to pre-order to use the service. Accordingly, when accessing the website of Starlink, users can easily choose familiar cities of Vietnam such as Hanoi, Ho Chi Minh City, Hue, Da Nang, Hai Phong, Can Tho … to register for history. use this service. Startlink will start providing satellite Internet services to users in Vietnam in 2022. However, to be one of the first users, users have to pay a fee of 99 USD (about 2.3 million VND) to “book”. Payment will be made via international cards such as VISA, Master Card. The kit offered will include a Starlink satellite pan, WiFi router, power supply, cable, and rack. In case of change of mind, Starlink will refund the deposit to the user. Assoc.Prof.Dr Pham Anh Tuan, Director of the Vietnam Space Center, said that Starlink is a satellite constellation project, in which thousands of small satellites are launched into low Earth orbit (abbreviated as LEO – Low Earth Orbit), located 550km from the ground. Internet signals will be shot from satellites straight down to receivers on the ground, then these devices will broadcast the signal through the local system or directly via wires connected to the customer’s Starlink router. The strength of satellite Internet is breaking down distance limits. Hilly areas, islands, complicated difficult terrain … still have simple internet access Satellite Internet works similarly to cable Internet, except that the system has more moving elements. When the customer accesses, the data request will be transferred from the computer to a satellite internet pan. This pan will broadcast a data request to a satellite orbiting the Earth. At this point, the satellite will send the received request to the ISP. The data is transmitted from the carrier to the satellite, then from the satellite to the satellite Internet pan, down to your router and into the computer. The more satellites, the more stable the signal. These satellites act like base stations, except that they are not obstructed by topographic space. Competition between suppliers According to Assoc.Prof. Dr. Pham Anh Tuan, the appearance of the SpaceX provider will create fierce competition from today’s telecom businesses. However, the bigger problem is that we do not have legal bases to manage cybersecurity for foreign suppliers. Therefore, in the coming time, there will be a need to consider legal frameworks to manage network information security, avoid bad and negative information, affecting socio-economic security. Assoc.Prof.Dr. Nguyen Huu Thanh, Director of the Institute of Electronics and Telecommunications, Hanoi University of Technology, this technology will create a big competition with network operators. Currently, Vietnam’s Internet is also relatively good, has coverage in remote areas, islands, but not as flexible as satellite Internet. Starlink is faster than optical fiber depending on the provider, but it is known that the bandwidth of the satellite Internet is very large, so it will compete greatly with current providers. The important point to compete here is the fee charged by the satellite internet provider, if it is too high, it will also be difficult to attract users. According to Assoc.Prof. Dr. Nguyen Huu Thanh, when the entire Starlink satellite system is put into orbit, this service will provide almost global coverage to populated areas. Users using the service only need to buy a pan to catch the waves, like a pan to watch TV. As for cybersecurity, if we talk about hacker intrusions and users, each person must be equipped with tools to protect themselves. Therefore, this problem is the same as with Vietnamese carriers only. The most important thing is to have fair competition policies, otherwise this market will be lost to foreign hands According to experts, Starlink can have coverage to the country or not depending on the country’s regulations. Currently, many countries have allowed Starlink to operate, but China and Russia will require the service to comply with special rules if they allow Starlink to broadcast on their own frequencies. Some countries prohibit the purchase, sale and use of ground-mounted Starlink receivers. In Vietnam, to manage satellite Internet, it is necessary to soon have appropriate regulations. In terms of feasibility, the cost of Internet services from the orbital satellite cluster is as low as that of Starlink is still 7-8 times higher than the price of fixed broadband Internet service in Vietnam. In the case of being deployed in Vietnam, satellite Internet service will be the solution to the problem of Internet coverage in areas with divided terrain such as hills, islands … In addition, the provision of satellite Internet services using low-orbit satellite beam technology promotes the development of the maritime and aviation industries.

A global customer survey conducted by Statista shows that Vietnam has the second highest cryptocurrency usage rate in the world, after Nigeria.

With millions of dollars traded every month, cryptocurrency exchanges are a good prey for cybercriminals. Fraudulent acts on electronic transactions include developer and investor information collection; attack with malware, phishing, malicious code, fake notification, navigate to fake website, DDoS … and steal electronic wallet security key.

A notorious cybercrime gang that targets cryptocurrencies is Lazarus and its members. Since 2019, Kaspersky researchers’ investigations show that Lazarus is behind the recent attacks in Singapore.

BlueNoroff, “family member” Lazarus specializing in the financial attack, is also said to be carrying out cryptocurrency-related attacks in Southeast Asia under the name SnatchCrypto.

The gang targeted banks, and was also accused of being involved in the theft of $ 81 million by Bangladeshi banks. Kaspersky researchers have been tracking SnatchCrypto since the end of 2019 and found that the guys behind the campaign have resumed operations with a similar strategy.

Chris Connell, Managing Director of Kaspersky Asia Pacific said: “In the near future there will be more new crypto investors across Southeast Asia as the bargains from different cryptocurrencies are undeniable, and Vietnam is one of the countries that are at the forefront of this transformation.

The development of cryptocurrencies is an integral part of digital transformation in the region and in Vietnam, so we encourage individuals who access these financial technologies to have a basic knowledge of security measures to keep our cryptocurrency safe ”.

Experts at Kaspersky share some basic ways to protect yourself against cybercriminals on cryptocurrency exchanges:

– Transaction research: Before investing, learn about cryptocurrency exchanges. These platforms provide the means for buying and selling virtual currency units, but there are over 500 transactions to choose from. Do research, read feedback and talk to experienced investors before going any further.

– Know how to keep your virtual currency: After purchasing cryptocurrency, you need to keep it. There are different types of wallets, each with different benefits, technical requirements and security. When trading, you should research your storage options before you invest.

– Diversification of investment: Diversification is the key to any smart investing strategy, and so is when you invest in cryptocurrencies. Don’t put all your capital into Bitcoin just because it’s the only name you know. There are thousands of options, and it’s best to divide your investments by a few different currencies.

– Prepare for instability: Cryptocurrency is a volatile market, be prepared for volatility. You will see amazing fluctuations in prices. If your investment ability or mental health cannot tolerate volatility, then cryptocurrencies may not be a wise investment.

Cryptocurrency is booming, but it’s still in its infancy. Investing in something new always presents challenges, so be prepared. If you are planning to invest, do your research carefully and invest carefully.

– Always give security: Transacting using your home network is safer than using a public network, but you need the right security. For starters, it’s a good idea to change the default router password because the root password is usually the same for all routers of the same model, making your WiFi vulnerable to attack.

In any case, it is best to do all electronic transactions over an encrypted VPN channel, which will add an extra layer of security.

When choosing a VPN service, pay attention to the connection speed (depending on the number and quality of the server group of the provider).
